Mea culpa Robert, I should have known better! I have an iPad that allows one to zoom right in at it, you'd swear that that screw is a square drive when viewed on the iPad. To double check myself, I then went and logged on with my laptop, saved your pic and then zoomed in to determine that I was wrong and you are right--sorry. Nonetheless, it is misaligned in your pic--I trust you straightened it out!
